Возможно, вам придется немного подправить, но это поможет вам: 

import os
import requests
import re
from bs4 import BeautifulSoup
import json
import shutil
import pandas as pd

url = 'https://doaj.org/public-data-dump'
response = requests.get(url)
soup = BeautifulSoup(response.text, 'html.parser')

options = {1:'Journal',2:'Articles'}
choice = int(input('What would you like to search for?\n1: Journals\n2: Articles\nEnter 1 or 2 -> '))

link = 'https://doaj.org' + soup.find('a', text=re.compile(r'Download all %s' %options[choice]))['href']

def download_url(keyword, link, save_path, chunk_size=128):
    output = []
    before = os.listdir(save_path)
    r = requests.get(link, stream=True)
    filename = save_path + '/temp.tar.gz'
    with open(filename, 'wb') as fd:
        for chunk in r.iter_content(chunk_size=chunk_size):
            fd.write(chunk)

    extract_path = save_path
    shutil.unpack_archive(filename, extract_path)

    os.remove(filename)
    after = os.listdir(save_path)

    newFolder = save_path + '/' + list(set(after) - set(before))[0]
    jsonFiles = os.listdir(newFolder)

    for idx, file in enumerate(jsonFiles):
        print ('Filtering for keyword "%s": File %s of %s' %(keyword,idx+1, len(jsonFiles)))
        with open(newFolder + '/' + file) as json_file:
            jsonData = json.load(json_file) 

        for each in jsonData:
            if 'keywords' in each['bibjson']:
                keywordsList = each['bibjson']['keywords']
                if any(keyword in x for x in keywordsList):
                    output.append(each)

    shutil.rmtree(newFolder)

    return output






save_path = os.getcwd()
keyword = 'covid'
jsonData = download_url(keyword, link, save_path)


titleList = []
authorList = []
yearList = []
linkList = []

for each in jsonData:
    w=1
    try:
        title = each['bibjson']['title']
        titleList.append(title)
    except:
        titleList.append('')

    try:
        authors = ', '.join([ x['name'] for x in each['bibjson']['author'] ])
        authorList.append(authors)
    except:
        authorList.append('')

    try:
        link = each['bibjson']['link'][0]['url']
        linkList.append(link)
    except:
        linkList.append('')

    try:
        year = each['bibjson']['year']
    except:
        year = ''

    try:
        volume = each['bibjson']['journal']['volume']
    except:
        volume = ''

    try:
        number = each['bibjson']['journal']['number']
    except:
        number = ''

    try:
        startPage = each['bibjson']['start_page']
    except:
        startPage = ''

    try:
        endPage = each['bibjson']['end_page']
    except:
        endPage = ''

    yearStr = '%s;%s(%s):%s-%s' %(year, volume, number,startPage, endPage)
    yearList.append(yearStr)


df = pd.DataFrame({'Title':titleList,
                   'Author':authorList,
                   'Year Post':yearList,
                   'Link Full Text':linkList})

Вывод: 

print (df.head(10).to_string())
                                               Title                                             Author             Year Post                                     Link Full Text
